phones and primary brain cancer, glioma, meningioma, or acoustic neuroma, tumors of the brain
or salivary gland, leukemia, or other cancers. None of the studies demonstrated the existence of
any harmful health effects from wireless phone RF exposures. However, none of the studies can
answer questions about longterm exposures, since the average period of phone use in these
studies was around three years.
5. What research is needed to decide whether RF exposure from wireless phones poses a
health risk?
A combination of laboratory studies and epidemiological studies of people actually using wireless
phones would provide some of the data that are needed. Lifetime animal exposure studies could
be completed in a few years. However, very large numbers of animals would be needed to
provide reliable proof of a cancer promoting effect if one exists. Epidemiological studies can
provide data that is directly applicable to human populations, but ten or more years follow-up may
be needed to provide answers about some health effects, such as cancer. This is because the
interval between the time of exposure to a cancercausing agent and the time tumors develop — if
they do — may be many, many years. The interpretation of epidemiological studies is hampered
by difficulties in measuring actual RF exposure during day-to-day use of wireless phones. Many
factors affect this measurement, such as the angle at which the phone is held, or which model of
phone is used.
6. What is the FDA doing to find out more about the possible health effects of wireless phone
RF?
The FDA is working with the U.S. National Toxicology Program and with groups of investigators
around the world to ensure that high priority animal studies are conducted to address important
questions about the effects of exposure to Radio Frequency (RF) energy. The FDA has been a
leading participant in the World Health Organization International Electro Magnetic Fields (EMF)
Project since its inception in 1996. An influential result of this work has been the development of a
detailed agenda of research needs that has driven the establishment of new research programs
around the world. The project has also helped develop a series of public information documents
on EMF issues. The FDA and the Cellular Telecommunications & Internet Association (CTIA)
have a formal Cooperative Research And Development Agreement (CRADA) to do research on
wireless phone safety. The FDA provides the scientific oversight, obtaining input from experts in
government, industry, and academic organizations. CTIA-funded research is conducted through
contracts with independent investigators. The initial research will include both laboratory studies
and studies of wireless phone users. The CRADA will also include a broad assessment of
additional research needs in the context of the latest research developments around the world.
7. How can I find out how much Radio Frequency energy exposure I can get by using my
wireless phone?
All phones sold in the United States must comply with Federal Communications Commission
(FCC) guidelines that limit Radio Frequency (RF) energy exposures. The FCC established these
guidelines in consultation with the FDA and the other federal health and safety agencies. The
FCC limit for RF exposure from wireless phones is set at a Specific Absorption Rate (SAR) of 1.6
watts per kilogram (1.6 W/kg). The FCC limit is consistent with the safety standards developed by
the Institute of Electrical and Electronic Engineering (IEEE) and the National Council on Radiation
Protection and Measurement. The exposure limit takes into consideration the body's ability to
remove heat from the tissues that absorb energy from the wireless phone and is set well below
